FRANK HINMAN PIERIONT, OF HORLEY, ENGLAND, ASSIG-NOR TO LANSTON MONOTYPE MACHINE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF VIRGINIA.

LEADING ATTACHMENT FOR COMPOSINGr-MACHINES.

Specification of Letters Patent.

Patented Jan. 10, 1911.

To all whom it may concern:

Be it known that I, FRANK HINMAN PIER- ronr, a citizen of the United States, residing at- Horley, county of Surrey, England, have invented a certain new and useful Improvement in Leading Attachments for Composing-llachines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

r)This invention relates to a leading mechanism or attachment for type setting or composing machines and is particularly applicable to automatic machines, or machines the operation of which is controlled or governed by a pattern, record strip or controller.

The chief object of the present invention is to provide a simple and eflicient mechanism which, by occupying a minimum of space, will not encumber the machine or intcrfere with the operators view of the galley and line mechanism or the operation'thereof, and which can be brought into, or thrown out of, action automatically in response to a signal in the record-strip or controller; also in its application it will not of necessity call for structural alterations in the composing or setting machine to which itis attached, the attachment being such that the device can be readily turned out of the way when not in use, or quickly removed bodily from the machine.

In the accompanying drawings illustrating a preferred form of embodiment of said invention-Figure 1 is a plan view of the left half of a leadino attachment according to this invention, an showing it applied to an automatic type casting-and composing machine of well known construction. Fig. 1a is a similar view of the right half of said machine. Fig. 2 is a plan view similar to Fig. 1, but to a larger scale 'and showing the leading attachment separately. Fig. 3 is a front elevation of the mechanism shown in Fig. 2. Figs. l1, 5, 6 and 7 are sectional elevations of the mechanism according to Figs.

Q and 3, showing the parts in different positions which they occupy during the cycle of operations. Fig. 8 is an elevation showing a portion of the automatic actuating mechanism. Fig. 9 is a view of a portion of the record strip showing the perforation or signal which on its first presentation in the casting or type setting machine brings the leading mechanism into action, and upon its second occurrence, in the record strip, throws the leading mechanism out of action.

The same letters and numerals of reference wherever repeated throughout the drawings indicate the same parts.

The leading attachment includes as its principal elements a frame A detachably secured to the machine with which it-is associated, and provided with a magazine for leads represented by parallel bars A A2, one or more pushers in the form of a recessed slide or slides supported in Guides or bearings C on bars A A2 and 'orming a gate at the outlet or delivery end of said magazine; a spring actuated follower mounted on frame A and engaging the rear end of the column of leads in the magazine; actuating devices for the pushers mounted upon a moving part of the machine to which the attachment is applied and capable of being coupled with and uncoupled from said pushers at will; and controlling means for said actuating devicesl including starting and stopping devices H, the latter controlled by the record strip and actuated by a moving part of the machine to alternately couple and uncouple the actuating devices and pusher.

It is not intended to limit the invention in its application to any particular composing or type setting machine, but, for the purposes of illustration it is shown in the drawings annexed to this specification, and will be described as adapted and applied to the galley of a type casting and composing machine such as forms the subject of Patent- No. 625,998, dated May 30, 1899, to the speciication of which patent reference may be had for a detailed description of the machine, as it is only considered necessary to refer here to parts more intimately connected with the leading attachment and the parts by which the leading attachment is brought into operation.

The casting and composing machine accordingto the aforesaid patent is controlled l by a pattern in the form of a' perforated record strip or controller and the perforations control, by the admission of air, the projection of pins by which a die case is The parts concerned, of the existing mechanism, are shown in Figs. l andla, wherein 1 indicates more or less diagrammatically the top plate of the machine. 2 is the die case containing rows of matrices which, by a compound motion of the die case in two Vdirections at right angles to one another, are

adapted to be centered individually over the casting mold (not shown, but which is situated beneath the member` 10.) 3 is the carrier for the die-case, and 4t the supporting frame for the die-case carrier. 5 is the actuating rod coupled to the die case; 6 a similar actuating' rod secured to the diecase carrier; 7 are the pins acting in coperation with the rod 5 by which the die case, by moving relatively to its carrier, is centered in one direction; and 8 are the pins cooperating with the rod 6, by which the die case carrier by ymoving in relation to the supporting frame at right angles to the movement of the die case, centers the diecase in the other direction; the pins of both sets are actuated pneumatically; 9 is the main actuating lever for lifting and lowering the die-case; 10 is the die centering pin lever to center the selected die; 11 is the paper tower and paper feed mechanism; 12 is'the cross bar containing the air ports communicating some with the pins of series 7 and others with pins of series 8, the pins being projected when perforations in the record strip coincide with their ports in the cross bar; 13 is the galley into which the completed lines of type are passed and arranged columnwise; 14 is `the line channel wherein the types of a line are assembled on delivery from the mold until the line is completed; 15 is the line carrier which by being reciprocated once at the end of the casting operations for each line conveys a completed line of types to the galley entrance; and J a vertically movable rule that normally closes the entrance to the galley and is raised t-o uncover said entrance when the line has been brought opposite thereto by the line carrier preliminary-to the advance ofthe line transferrer (not-shown) the latter operating to move the assembled line bodily into the galley. The line carrier 15, the line transferrer and the vertically movable rule J are all indirectly controlled by the perforations formed' at the end of the line in the record strip.

The main frame A of the leading devices,

I forming the subject of the present invention, is attached to the bed 1 of the composing machine in such a manner that the leads are carried in the guides or supports A A2 of the magazine directly over the entrance to the galley 13 of the composing machine. The frame A is secured to the bed l by two bolts 'a a which pass through lugs on the frameA and into holes in the machine frame 1. The lug a is formed in one with frame A and they lug at is attached thereto by a stud A3 so that by unscrewing this stud the entire attachment can be turned around, 011 the bolt a as a pvot, out of the way when not in use or when it is required to gain access to the parts of the composing machine situated at or near the entrance of the galley or the line assembly channel. The leading attachment is situated at a higher level than the galley so that it is out of the way of the mechanism acting in connection with the line channel and docs not interfere with the vertical movementI of the rule J and the transference of the line of composed matter from the line channel to the galley, while it leaves the channel and galley open to the view of the attendant. The guides or supports A A2 upon which the opposite ends of the leads rest, are in the form of channels, and one of these A is made adjustable relatively to the other so that the device can be adapted to receive leads of different lengths in accordance with the measure in which the matter is being composed. Conveniently the support A has secured to its underside a screw threaded post which passes through an opening a2 in the frame A and is secured in position in this slot by a clamping nut a5 or its equivalent. The leads in the magazine are constantly pressed toward the outlet by the lever D, to one end of which is pivoted a plate D or follower adapted to bear on the rearmost lead and at its other end the lever D has a slot Z through which a pivot pin D2 passes. The slot al allows the lever to be adjusted longitudinally in accordance with the length of the leads being used. A spring vD3 is secured at one end to a lug on the frame A and at its other end to a pin (Z passing through the slot (Z in the lever D thereby causing the lever to press constantly against the leads while the slot and pin connection allows for the aforesaid adj ustnient of lever D. A slot a. is formed in the wall ofthe support A for the passage of the lever D.

Opposite and contiguous to the outlet from the magazine for the leads are the reciprocating slides or pushers E, conveniently two in number, mounted in bearings in the two face plates or posts C on bars A A2. Under the action of the spring controlled lever D the leads are forced to the outlet B of the magazine and the slides or pushers are in their upper or normal position (see Fig. 7 when the foremost lead is forced against the front faces of the pushscopes ers E E which as shown are undercut or have projecting shoulders E2, so that when the foremost lead is pressed under the shoulders E2 and the pushers are moved downward the shoulders will engage the upper edge of the lead and force it down. The depth of the undercut portions is equal to the thickness of the lead, sothat when one lead is in position a second cannot be engaged by the shoulders and prevent the slides from descending. In their continued descent the pushers E E close temporarily the outlet of the magazine or holder so that another lead cannot move forward over the outlet or delivery opening between the pushers and ends of bars A A2 until the slides have been raised again, when another lead will be forced into the undercut parts of thc slides and held there by the pressure of the spring controlled follower D until the slides or pushers again move downward. These pushers normally stand in their upper position and are retained thus by the influence of the follower D acting through the leads, so that a lead is always in a position to be delivered by the pushers or slide. At their lower outer ends the pushers E E are provided each with a hook E3 with which the latch F engages to draw the slides downward and bring with them the foremost lead in the magazine.

The latch F (see Figs. 3 to 6 and 7) is actuated to engage the hooks E3 only when it is desired that a lead should be delivered.

Although latch F is raised and lowered each time a line is to be transferred from the line assembly channel to the galley, it is only permitted to actuate the slides E E when leading is required. At other times, although it is raised and lowered, it is held out of engaging position with the hooks E3 (see Fig. Conveniently the latch is carried by the reciprocating galley rule J which normally closes the entrance to the galley (see Figs. 1, 3 and 6) and acts as a support for the line in the line channel. This rule J acts in the same manner as the galley rule in the machine according to the aforesaid patent, the only difference being that whereas in the said machine the galley rule is solid, in the present instance it is slotted or is hollow, so that being situated immediately beneath the outlet of the magazine the lead engaged by the pusher is delivered into the slot in the rule and is guided down to the bed of the machine level with the galley and thus prevented from falling over on to its face. When the leading attachment is in operation, the mechanism which normally engages with the latch and holds it open or prevents it engaging the hooks E3 as above stated, is withdrawn so that the latch F snaps over the hooks E3 (see Fig. 4L) and on the return or downward movement of the slide J, carries the pushers E E with it.

The slide J is raised, conveniently by a cam, to the position shown in Figs. 41; and 5 when the assembled and completed line has been brought into line with the. entrance to the galley by the line-carrier 15, and when so raised permits the line to be forced laterally by the line transferrer into the galley.

0n the downward movement of the rule J with the latch F engaging the hooks E3 on the pushers E E, the lead which has its upper edge under the offsets on these slides, is drawn down beyond the iniiuence of the spring-controlled lever D and then falls down into the slot in the rule J, being meantime maintained in its upright or on-edge position by the walls of the slot. The lead being now within the rule J when the latter reaches its lower position, is in such a position that when the rule again rises to allow another line to be delivered from the line channel to the galley the lead remains behind and is thereby positioned between the line of types last delivered to the galley and the line for the reception of which the rule has been raised. The lead is pushed into the galley with the incoming line by the line transferrer, and the rule returns with another lead within it to be transferred to the galley, in the manner already described, with the succeeding line.

The latch F, as already stated, is carried by the rule J, to which it is hinged, as at f, and to render it effective or not edective there is provided at or near one end an outwardly projecting lever F (see Figs. t, v5 and 6) to which is pivoted one end of an upstanding rod or link F2 having its other end pivoted to the rule J, and a guiding link F3 is secured also to the rule and to the link F2. Normally the latch F is held in its closed position (see Fig. 6) by a spring F4. Adapted to project into the path of the rod F2 is a horizontally disposed rod Gr (Figs. 1 to (tand 8) which can be moved longitudinally and is carried in brackets on the frame A. At one extreme of its travel the end of this rod Gr forming the intercepter is in position to encounter the end of the rod F2, as shown in Fig. 5, so that when the rule J approaches the upper end of its travel, the rod F2 will be prevented from rising any farther, and, the rule J continuing to rise carrying with it the latch F, the latter is caused to turn on its hinges outward and assume the position shown .in Fig. 5, being thereby prevented from engaging the hooks E3 on the pushers E E. When the rule again descends, as shown in Fig. 6, and the line has passed into the galley, no lead is delivered, as although a lead has been forced into the undercut portion of the pushers it is held there by the pressure of the spring lever D, and the slides E E are also retained in their up position by the pressure of the lever D acting through the leads. Vhen, however, the rod G is at the other extreme of its travel, as shown in Figs. 3 and t, its outer end is withdrawn from the path of, hence does not encounter, the rod F2, so that the latch F, under the action of .its spring F4, snaps over the hooks E3 (see Fig. le) and when the rule J and latch F next descend the slides E E are drawn down carrying the lead which is in the -undercut portions E2 down free of the spring pressure, whence the lead drops to the level of the galley as already stated.

The starting and stopping mechanism H for actuating the rod G in the manner described is shown in Figs. 1, 3, 6 and 8. It comprises a disk H having two series of notches H2 H3 of different depths around its periphery, the deep notches H2 alternating with shallow notches H3. The notches are such that when one end of the rod G is in contact or is received in a shallow notch H3 the other end of rod G lies in the path of rod F2 of the actuating devices and when in engagement with a deep notch H2 the rod G lies outside said path so that it does not intercept the upward movement of the rod F2. A'spring G2, mounted between a collar on the rod G and one of the rod-carrying brackets, operates to force the rod G into contact with the periphery of t-he disk H and to return it from the projected to the withdrawn position. On the shaft h of the disk H is mounted a ratchet wheel H4 (see Fig. 8) with which engages a pawl H5 mounted on a bell crank lever HG loosely pivoted on shaft L. The pawl is mounted on one arm of the lever and to the other arm is pivoted a downwardly extending actuating rod HT which carries at its lower end a hook H8. This rod is maintained 'in its upper position by a spring H2 and is guided by a link Hlo pivoted to the rod and to a stationary support. lVhen the rod H7 is pulled downward, as hereinafter described, it rotates the ratchet wheel to the extent of one tooth so that the rod G, if it has been in engagement with a shallow notch H2 in the disk H, now enters a deep notch H2, the effect being, that the rod G is alternately projected and retracted by the intermittent or step-by-step rotation of the ratchet wheel H4 and disk H.

In order that the same leading device may take leads of varying thicknesses, also in order to prevent a lead passing too far into the undercut part of the slides, and thereby Vallow a second lead to partially enter and be engaged by the shoulders E2, the slides E E are each provided with detachable and interchangeable plates E4 (see Fig. 7) or stops. so that the different thickness of lead may be accommodated properly in the undercut portion of the slides with the face `of the lead in the undercut portion flush with the face of the slide.

In the type casting and composing machine to which the leading attachment, according to the present invention, is shown applied, the die case 2, as already stated, is centered over the mold by two movements at right angles to one another. After being centered, it is lowered to press the selected matrix firmly onto the top of the mold, and is raised, after the casting operation, to effect a subsequent centering. In the present embodiment, advantage is taken of the descent of the diecase 2 to effect the pulling down of the actuating rod H7, and for this purpose the die case is brought to a particular position for starting and stopping the leading device. It is a feature of the present invention that the same signal starts and stops the leading device alternately. The die case of the casting machine illustrated in the drawings is centered over the mold, the centering Vmovement being coutrolled by the pins of the series 7 and 8. The nose 2X of the die case 2 is utilized for engaging the hook H2 on the rod H7 (see Figs. 1 and 8) and the die case assumes thisposition of engagement when the matrix in one of the extreme corners is centered over the mold, in which position the die case is shown in Figs. 1 to 3 and 8. This position is one in which the die case is nearest to the rod H7 at the extremes of its movements in its two directions of movement and is the only one in which the nose 2*will engage the hook HS on rod H". l

At Fig. 9 is illustrated a portion of the record strip K for use in the casting machine described, and the perforations 7s therein denote perforations for producing various characters. The perforation K', however, is that which corresponds with poit 17 in the cross bar 12 on the casting machine and thereby admits air through perforat-ions K, port 17 and ducts indicated by line 18, to the underside of the end pin 7X in the block or series 7 so that the die-case is moved to its extreme left or first position, that is to say, the position to center the first matrix of a row, over the'mold. The die case is also moved to a position determined by the series of pins 8; it so happens that the position selected corresponds with the last row of matrices, hence requires no perforation in the record strip; the first matrix of the last row is thus indicated and centered over the mold. The reason why no perforation is required, corresponding to the end pin of series 8, to bring the aforesaid row of matrices in line with the mold cavity, is that this row represents one extreme position of .the die case in the direction controlled by the pin of series 8 and is indicated by a fixed pin.

These two movements bring the die case 2 into the selected position as already stated to engage the nose 2X with hook H8 before the die case descends, the subsequent descent effecting the pulling of rod H7 downward.

lt is apparent that the starting and stop ping device described may be controlled manually, if desired, but it is specially designed to be actuated automatically by the record-strip or pattern which governs the operations of the automatic casting so that the operations of the leading devices may be under the care of the composer of the record strip, and, there' fore, calling for no special attention on the part of the casting machine attendant. The record strip or pattern is prepared on a separate machine which is well known. As the present invention does not necessarily involve any alteration, rearrangement or modification of the record-strip preparing machine, it is not necessary here to enter into details of its construction or operation; suiiicient is it to say that it comprises a keyboard, the keys representing the same characters as find place in the die case of the casting machine, and these keys control a series of punches which perforate the record strip on a prearranged system. Such a machine is fully described in the specification of United States Patent No. 654,115. When the compositor operating such a machine, desires the matter composed to be leaded, he presses a signal key producing the required perforation K in the pattern or record-strip. As already stated, the signal selected, for convenience, is that shown in Fig. 9. The

compositor presses this key or produces the perforation K', both at the commencement and the finish of the composition of the record strip for the matter to be leaded. It is not necessary to repeat this leading signal with each line to be leaded, but only to produce it at a start and finish. As is well known, the record strip in the machines referred to is passed through the casting machine in the reverse order to composition, so that the last line composed is actually t-he first to be cast- The compositor, therefore, produces the leading signal which starts the leading device after he has composed the last line, and the signal which e'ects the stopping of the leading device is produced in the record-strip before the composition of the first line. As, in accordance with this in-l vention, the same signal is used to start as to stop the leading device, there is no liability of the compositor giving the incorrect signal. y

In the casting machine according to Patent No. 625,998, when the die case is placed in position to center the selected matrix block over the mold, a cast is made but with the present arrangement the air connections to the pin 7X will be so arranged that when the die 4case is in the leading position, the pump will be thrown out of action and no cast will take place.

Assuming the leading device to be out of action, the first presentation of the perforation K to port 17 of the cross bar results in the projection of pin 7X of series 7, and the die case 2 under the iniiuence of its centering mechanism acting on rods 5 and 6, takes up the position indicated in Fig. 1 in which the nose 2X of its central guide is directly over the hook H8 on rod H7. The die case having been centered, descends un- 'der the action of lever 9 and the nose 2X pulls down the rod H7 against the action of spring HS. The downward movement of the rod H7 causes pawl H5 to turn ratchet wheel H1 and disk H, allowing rod G to be retracted by spring G2 so that it does not intercept the upward movement of rod F2. The latch F, therefore, engages slides E E and draws them down. Leads are thus delivered automatically with each line until the second presentation to cross-bar 12 of the perforation K when rod H7 is again drawn down and wheel H4 and disk H moved through the distance of one more tooth, bringing a shallow' notch H3 into contact with rod Gr which is, therefore, projected and its ends caused to intercept rod F2 and prevent catch F engaging the hooks on slides E E.

As a modification, in place of the rod H7 being controlledthrough the die case from the record strip, a special air propelled pin may be provided to operate the rod through a pivoted lever or the like. In this case the pipefrom port 17 in cross bar 12 will lead to a. cylinder in which the special pin works, and the pin when first projected will effect the pulling down of the rod H7, to, say, start t-he leading device by turning ratchet wheel H4, and on its second occurrence will pull the rod H7 to again move the ratchet wheel H4 and stop the leading.

The lines of composition and the leads exactly fit the galley and it is, therefore, necessary that the lead positioned at the entrance of the galley be located accurately with reference to the sides of the galley, otherwise, one or the other of its ends will foul the walls of the galley. To insure this, a striker is employed which comprises, conveniently, a lever L pivoted at Z to a lug on one of the uprights C. The lever L extends downwardly, its lower end entering the slot in the rule J suiiiciently far to strike. when operated, the end of the lead within the slot in the rule J. An arm L is attached to the lever L and projects through the slot a2 in the frame of the leading device in position to engage the pivot pin or stud l5X of hook 15, when the latter advances. The stud 15X draws arm L back against the action of spring L2 until arm L overrides the stud when the spring L2 causes leverL to strike the lead within the rule and force it against the side wall of the galley.
